OmniGraffle
Updated: 04/26/2017 by Computer Hope
OmniGraffle is software that allows users to create diagrams and illustrations to express ideas visually. It's a tool for quickly creating professional-quality graphs and charts — especially flow charts — and exporting them to image formats like JPEG (Joint Photographic Experts Group), GIF (graphics interchange format), and PNG (portable network graphics). It is similar in many ways to Microsoft Visio.
OmniGraffle software is available for the Mac and iPad platforms.
